为什么控烟？

吸烟是一种危害健康的行为，它不仅对吸烟者本人的身体健康造成影响，还会对周围的人造成二手烟的危害。因此，控烟成为了一个非常重要的公共卫生问题。英文翻译：Why Control Smoking?

Smoking is a harmful behavior that not only affects the health of smokers themselves but also causes secondhand smoke harm to surrounding people. Therefore, controlling smoking has become a very important public health issue.

首先，控烟可以减少吸烟对人们健康的危害。烟草中含有许多有害物质，如尼古丁、焦油、一氧化碳等，长期吸烟会对人体健康造成很大的损害。控烟可以减少人们对这些有害物质的摄入，从而降低吸烟带来的健康风险。英文翻译：Firstly, controlling smoking can reduce the harm of smoking to human health. Tobacco contains many harmful substances, such as nicotine, tar, carbon monoxide, etc. Long-term smoking can cause great harm to human health. Controlling smoking can reduce people's intake of these harmful substances, thereby reducing the health risks brought by smoking.

其次，控烟可以保护被动吸烟者的健康。二手烟中含有许多有害物质，如焦油、尼古丁、苯并芘等，长期暴露在二手烟环境中会增加人们患上许多慢性疾病的风险。控烟可以减少人们在公共场所和家庭中的吸烟行为，从而保护被动吸烟者的健康。英文翻译：Secondly, controlling smoking can protect the health of passive smokers. Secondhand smoke contains many harmful substances, such as tar, nicotine, benzopyrene, etc. Long-term exposure to secondhand smoke can increase the risk of many chronic diseases in people. Controlling smoking can reduce smoking behavior in public places and households, thereby protecting the health of passive smokers.
